Title: Production of fructan composition
Inventor: SUZUKI SOJI
IPC: C08B37/18
Filed: 1990-03-30
Abstract: PURPOSE:To obtain a fructan composition improve in caking properties, deliquescence, water retention, browning, sweetness, digestibility, etc., by separating a fraction having a specified degree of polymerization from beta-2,1 fructan having a specified degree of polymerization. CONSTITUTION:A fraction having a degree of polymerization of 5 or below is separated from beta-2,1 fructan having a distribution of polymerization degrees of 1-10<6> by fractionation, for example, with an ultrafilter membrane of a fractionation mol.wt. of 2000 to obtain the purpose composition based on beta-2,1 fructan of a degree of polymerization of 10-10<6>. Because a membrane having the above fractionation mol.wt. of below 2000 has a high retention rate of a polymerization degree of about 4 and is not satisfactory for the fractionation, the purity of the obtained fructan composition is low. Because a membrane having a fractionation mol.wt. of above 2000 has a low retention rate of a polymerization degree of 5 or above, the yields of the obtained fructan composition is low.

Title: Oil separator for blow-by gas
Inventor: KATO TAKESHI
IPC: F01M13/04
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To improve the separation ratio of the engine oil included in blow-by gas by enlarging the contact area of the blow-by gas with a baffle plate. SOLUTION: A baffle board 6 is formed with a first collision section 7, in which through-holes 11 are made upper stream and a second collision section 8 downstream. Since the first collision section 7 is provided with the through- holes 11, and the first and second collision sections 7 and 8 are in parallel with each other, the flow of the blow-by gas falls into disorder, causing swirl flow. Therefore, the contact area of the blow-by gas with the baffle board 6 becomes large, which improves the separation ratio of the engine oil included in the blow-by gas. In addition, since the first and second collision sections 7 and 8 are formed integrally, the structure of the baffle board can be simplified, facilitating the manufacture of the baffle board 6.

Title: Control system for input/output device
Inventor: MOROTO SEIKOU
IPC: G06F3/06
Filed: 1979-06-29
Abstract: PURPOSE: To avoid resetting of the input/output device by other higher-rank device before sending up the interruption request, by not transmitting the start order to the designated input/output device in case the start order given from the different higher-rank device is detected.  
     CONSTITUTION: In data record control device DRC, each decode information to indicate the decoded 22 DRD (input/output device) to be selected is applied to one input terminal of AND gate group 26 respectively; and the output of assignment latch circuit 20 for SCD11 (staging disk control device functioning as higher-rank control device) is applied to the other input terminal of group 26. Thus in case the selection order is given from SDC10 to the DRD to which the assignment latch circuit is set by the order given from SDC11, the DRC does not give the selection order to the DRD but performs the internal process and reports to SCD10 that the DRD is now in use. Accordingly when an SDC monitors the interruption request due to the process end for a certain DRD, the DRD is never reset by other SDC.
